Analog Devices Inc. AD5245BRJ50-R2

Description
The AD5245 is a compact, 256-position digital potentiometer that offers a solid-state alternative to mechanical potentiometers. It features a small SOT-23-8 package (2.9 mm x 3 mm) and operates from a single supply voltage of 2.7 V to 5.5 V. The AD5245 provides enhanced resolution, reliability, and low temperature coefficient performance compared to mechanical potentiometers.
